  • v1.2.7 Patch Notes - 11 February 2017

    BALANCE - Endless levels now are not quite as endless. It's now much more difficult to last a half hour, an hour, or more, because the difficulty in those levels now scales faster the longer a level lasts. For instance, HP, spawning rate, speed, etc. all scale slightly faster over time. More enemies can appear onscreen at once in Raberata levels, and the Fear Points don't slow enemies as much in those levels. It should still be possible to last 10 minutes (to get the achievement for doing so), but now much harder / impossible to last an hour in one. - Made the "Love 3" medal campaign level easier. Not by doing anything to the level itself, but by increasing the cache reward for the "Love 2" level. Now instead of 160,000 bonus cache as a reward, the player gets 260,000 bonus cache instead. It's still a good idea to save up as much money in Love 2 as you can, but it should now be easier t…

  • v1.2.4 PATCH NOTES (December 8, 2015) - 8 December 2015

    v1.2.4 PATCH NOTES (December 8, 2015) Summary: This patch adds a new system where you can only have a limited number of medals active at any one time; this is intended to add more strategy to the medals system. There are also some other miscellaneous changes, such as a button to restore default settings and a button to turn the visuals down, and some changes that hopefully will fix a problem some people have been having with running out of VRAM (vertex buffer errors). As always, please report any bugs you find in the forums. - Imposed a limit on the number of Medals (achievements) that can be active at once; the base limit is now 4 plus 1 per completed campaign. This limit is displayed under the medals. Inactive medals are displayed in monochrome. When you get a new medal, it will start active, unless you are at the limit, in which case it'll start out inactive. To activate a medal, you…

  • v1.2.2 Patch Changes - 19 September 2015

    Major balance changes in this patch, to the Points, to some of the medals, and especially to the Point's achievement campaigns. A lot of other changes too, this is a pretty big patch. The patch changes are actually too big to fit in the text limit of an announcement, so here's a link to the discussions post that has the full patch notes: http://steamcommunity.com/app/298360/discussions/0/523897653308642078/ But a tl;dr version is: - Rebalanced many of the points various ways. - Made the Point Medal (Achievement) Campaigns easier. - Added descriptions of hotkeys and some other stats on the pause screen. - Made some changes to a few of the medal bonuses. - Some balance changes to some of the enemies. - Much more; read the full notes for the details.

  • Immortal Defense v1.2.1 Patch Changes - 8 September 2015

    Here are some changes for v1.2.1 (Sept 8, 2015). * - improved visibility of the upgrade price when the player cannot afford that price - improved visibility of Courage Point shots - added a Strategist Point range re-direction information into the Points manual, it appears now as " *Range "; I'd like also to have a visual representation of that range in the future - added hotkeys for game speeds: QWER for slow, normal, fast, fastest - fixed a bug that caused Panopticon's medal to be awarded when you killed a different type of enemy at 100% difficulty instead of just the Panopticon - fixed a bug that prevented Blaggenthorg's Skull medal from being registered with Steam. Unfortunately if you had this bug happen, for now, you will need to re-acquire this achievement in a new save file for it to be registered with Steam; I may make this easier in a future patch. - fixed a bug that caused the…

Short description

Immortal Defense is a story-driven tower defense game in which you give up your body and life to become an immortal "path defender", and defend your home world from destruction, forever. The game takes place over millions of years. Is there anything you would give up everything to defend?

About this game

Immortal Defense has been widely praised for the game's storytelling and unique twist on the tower defense genre, many consider it a cult classic of the subgenre. Its story was written by novelist Jeanne Thornton, and its universe is based on the novel Raberata by Robert Bisno. This new Steam release features many improvements over the original release: Steam achievements which grant gameplay bonuses, leaderboards, improved graphics and performance, widescreen support, an improved level editor, and much more. WARNING: This game involves a lot of flashing lights and visual effects. If you have sensory issues, such as epilepsy, this game might cause more problems for you than other games. There is a way to turn the visual options down, but even with all the options turned down, it can still be quite flashy. Immortal Defense has a story-driven campaign with 100 core levels and 50 optional side-quest levels (which can be completed for bonuses that help you with the core levels). The game takes about 20 hours to complete everything in. The game comes with the soundtrack, which is by Long Dao and classical composer Walter Eres. There are also Steam Cards which were hand-painted in watercolor just for this Steam release. There are 26 types of enemies, each with its own abilities and unique interactions with one another, and 11 types of towers, each of which goes through different forms as they are upgraded, and each of which gains new abilities as the player collects achievements. These are not standard enemy types like "flying" or standard tower types like "long range and slow"--you haven't seen these before in other tower defense games. The game also comes with a level editor, with Steam Workshop support, and is pre-packaged with an extra 62 levels created by fans. Note: The game was first released on May 31, 2007, and was updated with new content in 2009, and then again significantly improved for its Steam release in August 2015.

Steam marketplace comparison data

Price History Overview

USD uses SteamPulse's own locally recorded daily store snapshots, so this overview reflects the exact regional price history that SteamPulse has captured for this currency.

Coverage And Tracking Window

  • Snapshots: 1
  • Coverage: Sep 23, 2026 to Sep 23, 2026
  • Lowest observed: $9.99
  • Highest observed: $9.99

Immortal Defense's USD price history spans from Sep 23, 2026 to Sep 23, 2026, with 1 recorded snapshot across 1 calendar day. Each row records the available final price, listed base price, and discount metadata for that observation. Within this coverage the lowest recorded price is $9.99, the highest is $9.99, and the first visible tracked price is $9.99. These comparisons apply only to the snapshots SteamPulse holds; missing observations can contain changes that are not represented here.

For USD, SteamPulse uses locally captured regional storefront snapshots and does not reconstruct older prices with exchange-rate conversion. The chart and table show the values recorded for this exact currency from the stated coverage start. Additional snapshots extend that record, but they do not fill unobserved days or prove what the storefront displayed between observations.

Discount Windows And Sale Timing

  • Discount windows: 0
  • Discounted days: 0 days
  • Deepest markdown: No discount tracked
  • Latest sale window: No sale window tracked

Immortal Defense's tracked USD rows do not contain a discount window. This means no available snapshot in the stated coverage has usable discount metadata; it does not prove that the game was never discounted. Missing snapshots or archived rows without complete metadata can hide a sale, so SteamPulse does not infer pricing strategy from this absence.

If a later snapshot includes discount metadata, it will appear here with its recorded depth, price, date, and sale name when available. Until then, this section should be read only as a description of the available rows, not as evidence about the publisher's promotion policy.

Observed Price Changes And Stable Runs

  • Observed price drops: 0
  • Observed price rises: 0
  • Longest stable run: 1 day of uninterrupted daily tracking
  • Current run: 1 day of uninterrupted daily tracking

Outside rows carrying discount metadata, the tracked price has not recorded a separate price rise or drop yet. That means the observed undiscounted level has stayed stable across the snapshots SteamPulse currently holds. This is a statement about the recorded coverage only; it does not prove that an older or missing price change never happened.

The longest unchanged price stretch in the current record lasts 1 day of uninterrupted daily tracking at $9.99, from Sep 23, 2026 through Sep 23, 2026. Among rows without discount metadata, the longest unchanged run lasts 1 day of uninterrupted daily tracking at $9.99. The latest run records $9.99 for 1 day of uninterrupted daily tracking as the same recorded undiscounted price. Run lengths describe consecutive stored observations only and do not establish that a price is permanent.

Latest Snapshot And Sales Context

  • Current price: $9.99
  • Current list price: $9.99
  • Distinct observed prices: 1
  • Source mode: SteamPulse local tracking

The latest tracked snapshot records Immortal Defense at $9.99 in USD, with no active discount metadata. Across the available history SteamPulse has recorded 1 distinct final price in this currency. This supports comparisons with the lowest, highest, and most common values present in the retained record, subject to the stated coverage limits.

The live sales view and Steam sales record provide calendar context for these dates. A date overlap can be compared with a named Steam event, but it does not prove why a publisher changed a price. As new daily rows arrive, this overview recalculates its observed prices, discount windows, and run lengths automatically.
